    ok, so what is happening is that X-windows is sucking up all your cpu
    cycles for about ten seconds....during which time nothing else can
    happen..

    this is NOT normal...something is wrong...it can be fixed...with
    patience (let me suggest you not "try everything you can think of" to
    fix it....and, don't try every thing you find on the net that tells
    you how to fix it.....and, be VERY careful and look for the date of
    the postings, and the versions involved: lots of the info on openSUSE
    11.0 Xorg, display problems etc will NOT help with 11.3
    problems...been lots of display/X changes lately..

    i guess if you look at the logs you will find some hints...i am not
    sure the best places to look, maybe in one or more of these (i'm
    guessing....and, hoping someone else will tell you the _best_ places
    to look):

    /var/log/Xorg.0.log
    /var/log/messages

    finding the right log and the right error is gonna be key....let me
    guess that you will see the same or similar error or warning
    OFTEN...and, if you look at the computer clock when it freezes you
    should then be able to go into the (correct) log and find THAT
    date/time and learn what was happening..

    easy: on your desktop is a "My Computer" click it and find the section
    labeled (here) as "Disply Info", there you will find the vendor, model
    and driver(s) being used..

    i should have mentioned earlier....do not ignore James from
    Austin...he is looking at the problem from a different
    perspective--which may very well be the correct one!

    we do not _know_ what the problem is, yet...we just know the symptoms..

    I found the problem and it is video related.

    During the installation of OpenSuse 11.3 it used the "xorg-x11-driver-video-nouveau" driver which by itself *could* be fine. BUT, "BEFORE" updating I added the available community repositories i.e. Nvidia, Packman and so on. OpenSuse 11.3 installed the "nvidia-gfxG02-kmp-desktop" along with the "x11-video-nvidiaG02" but left the "xorg-x11-driver-video-nouveau" as you can see where I mentioned in an earlier part of this thread where Yast reported all 3 installed. The nouveau is an opensource driver so it should have been removed after the Nvidia driver was installed but it wasn't. Simply removing the nouveau driver solved the problem and 3D is working great and there is no more 10 second pause. So after all it really had nothing to do with AMD and the system is quite a nice upgrade from the core2 e6750.

    Thanks to those that responded and were willing to take their time to help me out. I hope this thread will be useful for somebody else in the future.

    CHEERS!
    Cheers!

    Interesting approach.

    What some of us also do is leave the 'xorg-x11-driver-video-nouveau' rpm in place and instead configure openSUSE such that the nouveau driver is not called. That can be done by running yast (you can run yast in text mode with root permissions if X window not available) and navigate to yast > System > /etc/sysconfig Editor > System > Kernel > NO_KMS_IN_INITRD and change it to "yes". This takes a minute or two to save once changed is submitted. In such a case (if proprietary driver is not yet installed) boot with the boot code 'nomodeset'. That will force loading of the older "nv" graphic driver for your hardware (which may or may not work).

    One can also blacklist the "nouveau" driver in the /etc/modprobe.d/50-blacklist.conf file. This can be done with root permissions by typing:
    Code:
         echo "blacklist nouveau" >> /etc/modprobe.d/50-blacklist.conf
    Note when there is a kernel update, the proprietary driver which is now in use could be broken (until a proprietary driver for the new kernel version is released) and at a time like that you may wish to fall back to another graphic driver. With your having removed the nouveau driver rpm, your choice in such a case may be to instead use the "nv" or the "vesa" or the "fbdev" graphic drivers.

    I feel compelled to post again because I didn't find the problem. For one night the solution I described worked but the next day when I started my system fresh, it was back to the 10 second pause. Like I said I recently installed 11.3 on two machines coming from 11.2 on my laptop(which was always fine) and 11.1 on my desktop (which was always fine as well). I found nothing but problems with 11.3 on two separate platforms *AMD&INTEL*.

    I decided I didn't want to spend anymore time trying to figure out why my system was behaving like it did so instead of trying to figure out 11.3, I waited for 11.4 and downloaded it TODAY(the day of it's official release) and must say that I am quite pleased. The issues I had in 11.3 are gone and everything seems so much faster and efficient. I do have a gripe about my sound card and will post it here since I started this thread in hopes that the moderators let it be, but aside from this one tiny detail, 11.4 is really stout compared to 11.3 on this system. I am an old has been for KDE 3.5 and still miss it but the newer 4.6 with OpenSuse 11.4 is really catching my eye.

    My one gripe about 11.4 Sound....I have an old SB Live 5.1 Card that I keep using because I can adjust the BASS and TREBLE which is essential. The Sound Configuration is much different on 11.4 and even though I uninstalled "pulse audio" like in the past, adding TREBLE and BASS to my mixer only gives me sliders that dont actually change anything. Same result if I go to Yast and adjust it there. My sound car is old. I have kept it because of the ability to adjust the Treble and Bass compared to any onboard sound. If anyone has a suggestion for a better Sound Card that would enable me to adjust these settings under Linux, I'll buy it tomorrow!

    Thanks!

    AND THANK YOU TO EVERYONE INVOLVED WITH OPENSUSE! 11.4 SEEMS AWESOME!!!

    i hope that NO one responds with any technical help to this new *11.4*
    sound question now buried in a *11.3* question thread without sound in
    the subject!

    and, please @cobaltss...work through the stickies at the top of the
    multimedia forum *before* you post your new problem in a new thread in
    the correct forum, with a descriptive subject line..

    thanks!

    cobaltss, please just start yourself your own thread, with this new problem in the thread name so others will know what the issue is about. I normally look at the thread title and decide if I can help based on that information. If the title does not relate to your issue, someone with a possible solution to your unspecified problem might pass you by.

    Don't get mad, geta new thread instead.

    Thank You,
